like, of labels that have been previously passed through a press andbeen prepared for the bronze by an impression of sizing as a basis ofadhesion.

To those familiar with the art to which this invention appertains, it iswell known that heretofore in the trade the labels have been passed byhand or by automatic conveyors to a bronzing machine distinct and moreorless remote fro-m the multi-color or other printing press of the bedand cylinder type, with the result that the labels are at leastpartially dry when received in the bronzing machine, thereby preventingthe bronze powder from properly adhering thereto while at the same time,either the services-of attendants are required in transferring thelabels from the press to the bronzing apparatus, or a very expensive andcomplicated system of mechanical transfer is employed which not only isliable to get out of order, but is troublesome to maintain. With aknowledge of these conditions as they exist today in the trade thus fardeveloped, the primary object of our invention is to provide a bronzingattachment for bed and cylinder multicolor printing presses which is soconstructed and arranged that it may receive the sheets directly fromthe cylinder of the press and effectively apply bronze immediately afterthey have been prepared by the sizing, so that the sheets will betreated before the sizing shall have had time to dry to any extent.

Another object of our invention is an improved bro-nzing attachment ofthe character set forth which will be of simple and durableconstruction, easy to maintain and not liable to get out of order,capable of being being applied directly to or at the cylinder of thepress, is so arranged that the devices which rub the sheet to cause theeffective adhesion of the bronze powder are automatically backed awayfrom the cylinder at predetermined intervals and in predetermined order,so that they Will be entirely out of the way of the gripping fingers andadjoining open parts of the cylinder when the fingers and such parts arepassing said devices. the rubbing devices being then automatically andin predetermined order moved forwardly into operative position wherethey will contact with the passing sheet. And the invention also aims togenerally improve and simplify bronzing apparatus so as to effecteconomies in the trade.

With these and other objects in view, as will more fully appear as thedescription proceeds, the invention consists essen tially in a bronzingattachment for multicolor printing presses of the cylinder and bed type,which may be readily secured to a press close up to the cylinderthereof, so as to apply and .rub in the bronze immediately after thesizing operation,

from the press to a separate and distinct bronzing machine more or lessremote from the press. And the invention also consists in certainconstructions, arrangements and combination of parts, that we shallhereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawings, in which:

Figure 1 is a side elevation of our improved bronzing attachment, thesame being shownin operative position relative to the cylinder of thepress; Fig. 2 is a similar view of the other side of the attachment;Fig. 3 is a transverse sectional view of the apparatus; Fig. 3 is asection in the nature of a diagram. Fig. 4 is a horizontal section onthe line 4.4 of Fig.1; Fig. 5 is a detail perspective view of acutofiforthebronze fountain; Fig. 6 is a detail sectional View on the line6--6 of Fig. 2; Fig. 7 is a perspective view of one of the rubbing indevices; Fig. 8 is a transverse sectional view through such device; Fig.9 is a detached perspective view of the rubbing rollers employed inconnection with the devices illustrated in Figs. 7 and 8, and also aviewof some of the actuating and retracting devices for such rollers;Fig. 10 is a detail perspective view of the distributing and applying orfeeding rollers, and Fig. 11

is a perspective view of the fountain and.

doctor rollers and their actuating devices, together with a portion .ofthe screw conveyer which is designed to feed the bronze to the fountain.

Corresponding and like parts are designated by similar characters ofreference throughout the several views.

Referring to the drawings, the numeral 1 designates the cylinder of amulti-color printing press, driven in any desired way, as it is to beunderstood that our invention comprehends an attachment which may beeasily applied to any bed and cylinder press. without altering theconstruction of the press and without interfering in any way with itsordinary functions. In the present instance, for the purposes ofillustration, the'cylinder 1 is shown as provided with a gear wheel 1meshing with an idler pinion 2 that in turn meshes with a pinion 3 onthe drive or power shaft 4, the latter receiving its motion in anydesired way, as from an electric motor (not shown) through theinstrumentality of a driving belt 5.

6 designates the bed of the press.

The cylinder 1 carries the ordinary internally actuated sheet grippingfingers 8 designed to engage the sheets as they pass down the feed table7, the sheets after being treated being finally deposited on the usualslatted frame 9 secured'to a shaft 10 which is oscillated atpredetermined intervals by the pinion 11, rack segment 12, connectingrod 13,- lever 14, and pinion 15, which latter is geared to the pinion'3 through the interposed spur pinion 16.

The supporting frame or casing of our improved bronzing attachment maybe of any desired construction and design, so'long as it is capable ofsupporting and housing the various elements of the mechanism, saidcasing being preferably shut in or inclosed on all sides except where itfaces the cylinder 1, so as to prevent the bronze from flying about andbeing wasted. In the present embodiment of the invention, this casingincludesside plates 17 that arecurved on their forward edges in the arcof a circle corresponding to the periphery of the cylinder 1 and a back18 which may be secured to the side plates in any desired way, and whichmay be removable, if desired, so as o gain access to the interior of thecasing whenever required without removing the entire attachment from thepress. Curved bands 19 are disposed on the outer sides of the plates 17at the forward curved edges thereof, said bands preferably carrying feltlinings 20 designed to lie against the periphery of the cylinder 1 atthe ends thereof so as to prevent the bronze from sifting out at thesepoints, said bands being secured at the top and bottom to relativelyshort rods or bolts 21 working in apertured lugs 22 formed on the sideplates 17. These bolts 21 are encircled by expansion springs 23 bearingagainst the lugs and the ends of the bands, and each band is formed atits middle with an apertured ear 24 designed to receive a pin 25projecting outwardly from the adjoining side plate, this constructionand arrangemerit of parts permitting the bands 19 to yieldingly rock andthereby compensate for the slight upward movement which is intertendinglongitudinally of the casing within.

the latter, and is fed into said trough from a hopper 29, the bronzebeing preferably continuously fed from the trough 28 by means of aspiral conveyer 30 secured to a 'shaft 31, said shaft being provided atone end with a sprocket wheel 32 over which a chain 33 passes. Thischain also passes around asprocket wheel 34 on a longitudinallyextending shaft 35 journaled in the side plates 17, said shaft carryinga sprocket wheel 36 connected by a sprocket chain 37 to a sprocket wheel37 on the shaft of the cylinder 1, the sprocket wheels 36 and 37 beingpreferably so proportioned that the latter will make two revolutions toone revolution of the former. As the bronze leaves the trough 28, itpasses into and through'a downwardly inclined laterally elongated spout38, from whence it passes by gravity into a fountain 39, which extendsfrom one side'plate 17 to the other, at the bottom of the casing. Afountain roller 40 is mounted in the fountain 39, and is engaged by acutoff 41 which, as best illustrated in Fig. 5,

is constructed in two parts or sections, al-

vention is not limited in this regard, said cut-off being formed at itsends with trunnions 42 by which it is journaled, and the sections beingprovided with any desired number of tensioning bolts 43 Working througha bar 44 extending longitudinally of the casing and secured at its endsto the side plates 17 thereof. By adjusting the tension of the bolts 43,the amount of bronze passed out by the fountain roller may be regulated.The fountain roller 40 is intermittently actuated, the shaft of saidroller having a ratchet wheel 40 secured to it' at one end, said ratchetbeing engaged by a pivoted pawl 41 carried by the arm 42 loose on theroller shaft, and a crank 42 is secured to said arm 42*, said crankbeing connected by a pitman 43 to an eccentric disk 44*" secured to oneend of the shaft 35. (See Fig. 11.)

The fountain roller 40 is preferably co ered with plush or the like, andco-acting with it is adoctor roller 45, preferably of composition, theshaft 46 of the roller passing out through and working in slots 47 thatare formed in the side plates 17. The ends of the shaft 46 are carriedby the upper ends of substantially vertically disposed rocker arms 48and 49 mounted on the outer sides of the plates 17, as best illustratedin Figs. 1 and 2, and secured to the ends of a longitudinally extendingrod 50 journaled in said plates. The arm 49 is formed with a downwardextension 51, to which a contractile spring 52 is connected at one end,the other end of said spring being fastened in any desired way to somestationary portion of the mechanism, whereby the spring will exert atendency to rock the arms 48 and 49 in a direction to carry the doctorroller 45 from contact with the fountain roller 40. The roller 45 isintermittently and positively moved in the opposite direction, that is,into contact with the fountain roller 40, by means of a link- 53connected at one end to the downward extension 51 of the arm 49, and atthe other end to a lever 54, pivotally connected at its upper end 55 tothe adjacent side plate 17, said lever carrying a roller 56 designed forengagement by a cam 57 on the shaft 35, this positive movement of thedoctor roller serving to swing it from contact with the fountain roller40 into contact with a distributing roller 58 which is, in the presentembodiment of the invention, held continuously in contact with thebronze applying roller 59. Preferably, the rollers 58 and 59 are coveredwith plush or some equivalent fabric, and are geared together by thepinions 60, as best illustrated in Figs. 2 and 10, the roller 59 beingnormally in contact with the periphery of the cylinder 1 or the sheetheld-thereon; such contact being only broken when, in the continuousrotation of said cylinder, the same has imparted to it a the bronze intothe sized portions of the I sheet immediately after the bronze isapplled thereto by the roller 59 is performed bya laterallyreciprocating bar 61 having its working face covered with beaver fur 62or some equivalent soft substance. This bar 61 is secured at its rearside to any desired number of rods 63, there being three of these rodsin the present instance, as illustrated in Fig. 4. The rear ends of therods 63 are inserted in blocks 64 that are secured by set screws orsimilar fastening devices to a laterally reciprocating rod 65, the rod65 being provided at one end with a bearing block 66 working through oneof the side plates 17 and being provided at its other end with aneccentric strap 67. The strap 67 accommodates an eccentric roller 68which is carried by a disk 69 secured to the forward end of ahorizontally disposed shaft 70 journaled in bearings 71 formed on theouter face of one of the side plates 17. The shaft 70 carries a spiralgear 72 meshing with a corresponding gear 73 secured to the outer end ofa longitudinally extending shaft 74. The other end of the shaft 74carries a sprocket wheel 75 connected by a chain 76 to a larger sprocket77 carried by the shaft 35.

In order to automatically move the continuously reciprocating bar 61back from the cylinder 1 at predetermined intervals,

we have provided the following mechanism:

Each of the blocks 64 has secured in it a bushing 78 and is recessed onits rear side to accommodate a recessed section 79 which operates in thenature of a crank and which is fastened to the bushing by a set screwand pivotally connected to the rear end of the rod 63, as bestillustrated in Fig. 8. The bushings 78 of the blocks 64 are grooved toreceive splines or feathers 80 formed on a rod 81 extendinglongitudinally in the framework back of the rod 65, one end of the rod81 extending to the outside of one of the plates 17, and carrying acurved arm 82. The arm 82 is fixed on the rod 81 and is securedintermediate of its ends to one end of a contractile spring 83, theother end of said spring being secured to the adjoining side plate. Aroller 84 is carried by the upper free end of the arm 83, said roller,as best illustrated in Figs. 1 and 9, being designed for engagement by acam 85 secured to a shaft 86 journaled in the side plates, said shaftcarrying a gear wheel 87 which meshes with a gear wheel 88. The gearwheel 88 in turn meshes with a gear wheel 89 on the shaft 35. By thismeans the continuous rotation of the shaft 86 will,

'- turn the rod 81 so as to positively carry the bar 61 forwardly andhold it with its work- 7 ing face against the cylinder 1 or sheet carried thereby. As soon as the cam 85 leaves the roller 81, the spring 83will be permitted to act and it will pull the arm 82 rearwardly, thisresulting in turning the rod 81 to rock the cranks 79 rearwardly so asto draw the rods'63 rearwardly in the blocks 61 and move the'bar 61 awayfrom the cylinder. This action takes place without any cessation in thereciprocating movement of the bar 61, as the blocks 64 are splined onthe rod 81, as before described.

The secondstep in the process of rubbing the bronze into the sizedportions of the sheet while it is passing through the attachment on theprinting cylinder 1, is performed by a roller 90, and the final step inthis'operation is performed by a corresponding roller 90*, the. roller90 being mounted above the bar- 61 and the roller 90 above the roller90. Both of these rollers are preferably covered with beaver fur, likethe operative face of the bar 61.

91 designates the shaft of the roller 90 and 91 designates the shaft ofthe roller 90. Each of these shafts is journaled at its ends ineccentric bearings 92 carried by the side plates 17 whereby when apartial rotation is imparted to said bearings, the rollers will bebacked away from or carried forwardly against the cylinder 1 or sheetthereon, at predetermined intervals and in succession, the movementbeing diagrammatically illustrated in Fig. 3. The rollers are, however,continuously rotated, in the present embodiment of the invention, aboutthe shaft 91 of the roller' 90 carrying atone end a sprocket wheel 93,.and the corresponding end of the shaft .91 carrying a sprocket wheel 94.the sprocket chain 95 passing around the said wheels 93 and 94 andaround a. sprocket wheel 96 secured to the adjoining end of the shaft74. To secure these automatic movements of the rollers 90 and 90" towardand away from the cylinder 1 (referring now particularly to Fig. 9, andfirst to the roller 90), the bearings 92 of the shaft 91 have crank arms97 connected to them. The arms 97 are pivotally connected by links 98 torocker arms 99 secured to a longitudinally extending shaft 100 mountedin the side plates 17 and contractile springs 101 are secured to therocker arms 99 and to the side plates 17, tending to move said rockerarms in such a direction that the crank arms 97 will be swung around tocarry the eccentrically mounted shaft 91 away from the cylinder 1. Oneof the rocker arms 99 is joined to a lever 102 extending rearwardly fromthe rod 100 and carrying a roller 103, said roller being designed forengagement by a cam 104 on the shaft 86, whereby as said shaft rotates,the engagement of the cam 104 with the roller 103 will result in movingthe rocker arms 99 against the tension of the springs 101 so as to turnthe eccentric bearings 92 in a direction to carry the roller 90forwardly against the cylinder 1. Correspondingly, the bearings 92 forthe shaft 91 have crankarms 105 secured to them, said crank arms beingjoined by links 106, to rocker arms 107, to which contractile springs108 are connected. The arms 107 are secured toa rod 109'to which a lever110 is also connected, said lever carrying a roller 111 designed forintermittent engagement by a cam 112 on the shaft 86, the cams 10 1 and112 being so timed that the former will work in advance ing 118, andoperated to suck the loose bronze out from the casing, whence it may bepassed to the ordinary bafile box or, if desired, passed by the tube 119to the hopper 29. The, side plate 17' distant from the fan may be formedwith a screened opening 120. The rollers 90 and 90 are cleaned by meansof cleaning rollers 121 that are journaled in side plates 17 contiguousto the rollers 90 and 90*, each of the cleaning rollers 121 being formedwith any desired number of kerfs or grooves disposed longitudinallytherein and designed to receive and hold, by

any desired means, cleaning strips which I may be of any desiredcharacter but; which are preferably formed of wire fabric in doublelengths with the doubled edges outermost, as indicated, at 121*. Theshaft of each of the rollers 121 is provided at one end with a sprocketwheel 123 and sprocket chains 123 pass over these sprocket wheels andover corresponding sprocket wheels 122 secured to the adjoining ends ofthe shafts of the rollers 90 and 90 It will, of course,

be understood that the rollers 90 and 90 .ing rollers 121 will be out'of engagement with the peripheries of the rollers 90 and 90; when saidlast-named rollers move back-' wardly or away from the cylinder 1, theirperipheries will come into contact with the rapidly revolving wirefabric cleaning strips, and the same will effectively clean theperipheries ofthe rollers 90 and 90 of the bronze which would otherwiseadhere thereto. This bronze may be readily removed as it comes off therollers 90 and 90 by means of suction boxes 123 which are mounted injuxtaposition to the cleaning rollers 121 within the casing and whichhave pipe connections 123 with the main fan 117, whereby 'said fan maynot only suck the loose or excess bronze from the other partsof thecasing, but will also act to directly carry the bronze from the rollers90 and 90 and the cleaning rollers 121 before described. The casing ofthe suction fan 117 is connected by means of'a duct 119, shown in inFig. 2, to the hopper 29 and thus returned to the font. Thus noneof thefine dust of the bronze is ejected into the room or lost but acontinuous circulation is kept of the bronze, the bronze being appliedfrom the font to the paper, rubbed in, dusted therefrom by the rollers90 and 90*, then taken therefrom by the cleaners 121 and 121 and thencedrawn into the suction tubes 123 and 30 from thence passed back'to thehopper again.

Furthermore it will be seen that these suction tubes not only take thebronze powder from the rolls 9 and 90*, but that they will act to drawin any loose bronze powder fl0ating inthe air inclosed within thecasing'of the apparatus. This not only eliminates waste, but is far moresanitary than the or. dinary operation. Furthermore inasmuch as the fontis located at the lower portion of the casing, the bronze as it is takenfrom the font'does not fall down through the casing as it would beliable to do were the font located at the upper portion of the casing.It is to be understood that our invention is rot limited to thisconstruction of means for directly removing the waste, and that separatefans may be provided, if desired, for conveying .the powder from thesuction boxes 123, but we prefer the use of the single fan 60 117 toserve all of these functions. Preferably, the rollers 90 and 90 arevibrated in opposite directions from each other and 1on gitudinally oftheir length at the same time they are rotated; As one means foreffecting this result, although it is to be understood that variousother means may be employed for this purpose, one end of each shaft 91,91 is provided with a grooved collar 124, said collars being engaged byan interposed cam 125 which is mounted on a stub shaft 126 secured toand projecting outwardly from the adjoining side plate 17. Movable withthe cam 125 is a sprocket wheel 127. A sprocket chain 128 passes over 66the sprocket wheel 127 and also over a dotted lines in Figs. 1 and 3 andin full lines sprocket wheel 129 secured to the adjacent end of theshaft 74, whereby as said shaft rotates, the cam 125 will be rotated toimpart the desired vibratory movement to the shafts 91 and 91 and therollers 90 and 90 70 From the foregoing description in connection withthe accompanying drawings, the operation of our improved bronzingattachment for multi-color or other label printing machines will beapparent, as the operations and correlated actions of the variouselements of the mechanism have been I described along with the detailsof construction and relative arrangements of the parts. But it may bestated, generally,-that in the so practical use of the apparatus, anintermittent movement will be imparted to the fountain roller 40 so thatthe latter will pass the bronze to the doctorv roller 15, and saidroller will, at predetermined intervals, vibrate between the roller 40and the distributingroller 58, conveying the bronze to f the latter,and-said roller 58 passing it to the roller 59 which will applyit to thesheet. The bronze will then be rubbed in by the laterally reciprocatingbar 61 and the rollers 90 and 90 At predetermined intervals,the sheetgripping fingers and the adjoining open portion of the periphery of thecylinder 1 will arrive at and commence to sweep past the bar 61 androllers 90 and 90, and at this time the bar and said rollers willautomatically move back from the periphery of the cylinder and will thenin turn be positively moved forwardly again into their operativepositions by the mechanism hereinbefore specifically set forth. andillustrated in the accompanying drawings.
